      Joint Real-Time Scheduling Methods for Deterministic Industrial
                          Field/Backhaul Networks

Abstract

   In industrial field/backhaul networks, joint real-time scheduling
   method is important to make end-to-end flows meet their deadline.
   This document proposes four joint scheduling methods, and these
   methods have considered four scenarios: time-slotted industrial
   backhaul network, regarding industrial backhaul network as a black
   box system, ignoring delay of industrial backhaul and establishing
   latency model of industrial backhaul network.

1. Introduction

   Industrial field network is a network that can be deployed in
   process control industry to monitor industrial field equipment for
   achieving the target of control and management. Industrial field
   network can improve production efficiency, reduce human intervention
   and decrease cost. It is significant for industrial modernization.
